Description

Technical Field

[0001] This invention belongs to the field of reagent mixing technology, and in particular to a reagent mixing device for chemical detection. Background Technology

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. Chemical reagents are indispensable in the daily work of factories, schools, hospitals and research institutes. In the process of testing chemical reagents, they need to be mixed by mixing devices.

[0003] Current chemical reagent mixing devices mostly use stirring shafts for mixing chemical reagents. However, stirring shafts tend to stir horizontally but lack vertical stirring, which may cause the chemical reagents to separate into layers, affecting the mixing rate.

[0004] Therefore, in view of this situation, there is an urgent need to design and manufacture a reagent mixing device for chemical detection to meet the needs of practical use. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reagent mixing device for chemical detection, comprising a mixing cylinder for mixing reagents for chemical detection and an outer shell, wherein a first moving rod is slidably connected to the upper side of the outer shell, a piston is fixedly connected to the side of the first moving rod, a connecting plate is fixedly connected to the end of the first moving rod away from the piston, a second limiting plate is rotatably connected to the lower side of the connecting plate, a second moving rod is fixedly connected to the lower side of the second limiting plate, a transverse stirring blade is fixedly connected to the side of the second moving rod, and a vertical stirring blade is fixedly connected to the side of the second moving rod.

[0007] Preferably, a rotating sleeve is sleeved on the side of the second moving rod, and a first limiting plate is fixedly connected to the side of the rotating sleeve.

[0008] Preferably, a cover plate is rotatably connected to the side of the first limiting plate, and a first motor is fixedly connected to the upper side of the cover plate.

[0009] Preferably, the output end of the first motor is fixedly connected to a rotating shaft, and a first spherical gear is fixedly connected to the side of the rotating shaft.

[0010] Preferably, the side of the first sprocket meshes with the second sprocket, and the interior of the second sprocket is fixedly connected to the outside of the rotating sleeve.

[0011] Preferably, an air intake pump is installed on the side of the outer casing, and an electric valve is connected to the side of the air intake pump.

[0012] Preferably, the end of the electric valve away from the air inlet pump is connected to an air delivery pipe, and an air outlet pump is installed on the side of the outer casing.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This chemical detection reagent mixing device, through an air inlet pump and an air outlet pump, drives the piston, the first moving rod, the connecting rod and the second moving rod to move up and down in a circular motion, which drives the horizontal stirring blade and the vertical stirring blade to move up and down, thereby driving the vertical stirring of the chemical detection reagent. At the same time, the first motor drives the first sprocket, the second sprocket, the rotating sleeve, the horizontal stirring blade and the vertical stirring blade to rotate horizontally, thereby realizing the horizontal stirring of the chemical detection reagent, avoiding the stratification of the chemical detection reagent and accelerating the mixing rate of the chemical detection reagent.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0024] To address the issue that mixing reagents for chemical testing often relies on stirring shafts, which primarily perform horizontal stirring but lack vertical stirring, potentially leading to reagent stratification and affecting the mixing rate, the following measures are proposed: Figures 1 to 4 The illustrated chemical reagent mixing device includes a mixing cylinder 1 for mixing chemical reagents and an outer shell 3. A first moving rod 4 is slidably connected to the upper side of the outer shell 3, and a piston 6 is fixedly connected to the side of the first moving rod 4. A connecting plate 5 is fixedly connected to the end of the first moving rod 4 away from the piston 6. A second limiting plate 14 is rotatably connected to the lower side of the connecting plate 5. The second limiting plate 14 is rotatably connected to the connecting plate 5 to facilitate pulling the second moving rod 15 for up-and-down cyclic movement. The lower side of the second limiting plate 14... A second moving rod 15 is fixedly connected to the side, a horizontal stirring blade 11 is fixedly connected to the side of the second moving rod 15, a vertical stirring blade 12 is fixedly connected to the side of the second moving rod 15, a rotating sleeve 16 is sleeved on the side of the second moving rod 15, the rotating sleeve 16 has a groove to facilitate vertical movement with the horizontal stirring blade 11 and the vertical stirring blade 12, a first limiting plate 13 is fixedly connected to the side of the rotating sleeve 16, the first limiting plate 13 is rotatably connected to the inside of the cover plate 2 to provide support for the first limiting plate 13.

[0025] A cover plate 2 is rotatably connected to the side of the first limiting plate 13. A first motor 18 is fixedly connected to the upper side of the cover plate 2. A rotating shaft 19 is fixedly connected to the output end of the first motor 18. A first spur gear 17 is fixedly connected to the side of the rotating shaft 19. A second spur gear 20 meshes with the side of the first spur gear 17. The interior of the second spur gear 20 is fixedly connected to the outside of the rotating sleeve 16. An air intake pump 7 is installed on the side of the outer casing 3. An electric valve 9 is connected to the side of the air intake pump 7. During operation, the electric valve 9 of the exhaust pump 8 is activated to transport air into the outer casing 3, pushing the piston 6 to move. When the exhaust pump 8 is working, the electric valve 9 of the intake pump 7 is activated to transport air to the outside of the outer casing 3, pulling the piston 6 to move, realizing the vertical cyclic movement of the piston 6, the first moving rod 4, the second moving rod 15, the horizontal stirring blade 11, and the vertical stirring blade 12. The end of the electric valve 9 away from the intake pump 7 is connected to the air supply pipe 10, and the exhaust pump 8 is installed on the side of the outer casing 3.

[0026] All structures and instruments are treated with heat-resistant and waterproof materials.

[0027] The intake pump 7, exhaust pump 8, electric valve 9, and first motor 18 are all conventional devices. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. They are all controlled by remote control switches. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0028] Working principle

[0029] In operation, this chemical testing reagent mixing device starts by activating the first motor 18, which drives the rotating shaft 19 and the first sprocket 17 to rotate. The rotation of the first sprocket 17 drives the second sprocket 20 to rotate, which in turn drives the rotating sleeve 16 to rotate. This causes the horizontal stirring blade 11 and the vertical stirring blade 12 to rotate horizontally. Simultaneously, the air pump 7 is activated to transport air into the outer casing 3. The air pushes the piston 6 to move, which in turn moves the first moving rod 4. The movement of the first moving rod 4 causes the connecting plate 5, the second moving rod 15, the horizontal stirring blade 11, and the vertical stirring blade 12 to move vertically. At the same time, the air pump 8 discharges the air from the outer casing 3.
